As shown on the drawin s: l

The reference numeral l, indicates a furnace as a whole which is constructed eX- teriorly in any preferred manner, and is provided with a suitable number of apertures 2, as shown, four in number, through which the material is inserted and withdrawn from the heatingchambers 3-.45 one located on each side of the center ofthe furnace, as shown clearly in Fig. 2. The interior of section showing the modified :the furnace is lined with fire brick of suitable kind, and the bottom fire brick is proas, for instance, rivets, from falling 'into a fire chamber 7. The

fire chamber 7, has the :pound curve, that is,

13, integral 'with the bottom and side walls peculiarly shaped and .arranged for deflecting the flame and heat to the desired part orparts of the furnace. AS shown, a centrally disposed deflector vrib 8, triangular' in cross-section, extends 'the full depth of the furnace, and from the bottom of said rib 8, walls 9, are formed in comare curved outwardly and upwardly from the base of the rib 8, then substantially vertical for a short distance, then curved outwardly, forming the retaining walls 5 and 6, before mentioned.

Anyv suitable top `or .covering 10, is provided, which has 'a downwardly opening axial passage centrally disposed over vthe de fleeting `rib or wall 8. Extending linto said passage is a universal burner which is so adjustable as todirec't the flame againstany point in the lire chamber. An air pipe 11, is shown, to which is connected at substantially rightsangles-a pipe 12, having aflano'e "lower end thereof. T ie flange 13 Yrotatably supports a 4part ofthe burnercomprising a pipe 14, having au upwardly directed exteriorly Ithreaded enlarged upper end or cup 18, adapted to fit over the flange 13, and 'to -receive a suitable packing 15, and jam washer 16, therein. The packing 15 and the washer 1G, are tightly clamped in place by a cap or collar 17, disposed around the pipe 12, and threaded on 1the upper end of Ithe cup 18. The lower end of the pipe 14, is provided with a flange 19, on which is supported the pipe '20. Said'pipe 20, is provided with au enlarged eXte'riorly threaded upper end or cup 21,between which andthe pipe 14, a suitable packing 22, and jam washer 23, are secured and firmly held in place to form a tight joint by means of the flanged collar Aor cap 24, which threads on `the cup Q1 end of ipe '20. A

'o'urnaled in the rotatable pipe 14, in any suitable manner, is a shaft or spindle 25, to which is secured a half butterfly valve Q6. A wheel 27, is secured on the outer end of said shaft and fastened Vto said wheel 27, is a spring arm or pawl 28, adapted to engage the marked segment 29, to hold the valve in any adjustment. An oil or gas supply pipe 80, Vconnects with any suitable source of sup- `ply, and is provided with a Vvalve 81, for

'controlling the supply therethrough. An oil or gas spraying nozzle 32, is attached to 'the pipe 30, and extends Vdownwardly in the air pipe 1Q, to within a suitable `distance above the butterfly valve. VSaid spraying nozzle, las Vshown in detail in Fig. i8., has a' plug 33, `in the fend' lthereof and apertures v34, open tangentially downwardly into a ydeflector and drip cup 85, secured on the end of the nozzle. n

In the construction shown in Figs. 9 to 12, inclusive, the furnace is constructed the same as hereinbefore described with the exa seat for the ball 39, on

being swung in any 'which leads to t j Aprovided with a controlling valve 43. Any

ception that the burner is constructed dif .ferently As show-n, an air 4pipe 36, extends through Vthe passage in .pipe being provided x1 'ith an externally threaded bossB', adapted to have a am nut 38, threaded thereon. The boss 87, and jam nut 88, are complementally ground to form the supply pipe 40, to form a ball and socketl joint, and said jarn nut is cut laway to'permit free movement of the pipe 40, in any direction. A downwardly directed nozzle 'or spray pipe 41, is secured to the inner end of the pipe 40,as shown. Y

For the purpose of permitting pipe `40, direction to direct the nozzle as desired, a pipe the source lof supply, and is standard Vcoupling 44, is *secured fto thejpipe '42, that will `permitfturningof the 'pipe 45, .and `said pipe 45, is 'likewi-se connected to `pipe 46,'-by means of 'afcou-pling 437, which will permit swinging motion 'of said `pipe A similareouplingf48,connects'pipesl and 49, and all of these couplings Fco-act 'to perrrbeing Vadjusted luniver-sally to ln Figs. 13 and 14, we "h'avejshown a 'modified 4form of fire chamber. Instead of a long 'fire chamber, as `shown in Fig-Q, we yprovide a -'circular orV round 'fire chamber which is shaped to provide lan upwardly directed cone deflector 50, from th'e bottom of which the wall 51 of the 'lire fcha'mber is curved downwardly, outwardly and upwardly. Said wall is 'substantially vertical for -a shortfdistance, outwardly curved wall "52. VRetaining walls 53-53 are provided to yprevent fthe articles the cover 10, saidv and terminates vin an being treated from falling into the lireV chamber.

The operation is as follows: Y Y ln the construction shown "in Figs. 1 to 8, inclusive, the articles to be heat trealted or heated 'are inserted into the heating 'chamibers 3 4, through the openings "-2, and Vwe will assume 4that 'the heat is desired to "bedi-Y rected uniformly Sto all points of the heating chambers. In this case, the butterfly valve is fully opened, and the valvel inthe `supply pipe 30, is opened. The `oil vor gas being under pressure `is admit-ted Ito the nozzle '32, and is sprayed 'through the apertures 34, and 'deflected by the lcup zd'efll'ector 35, outwardly against V'tlne walls gof the burner where the air from the pipe '11is `carbureteclwiththe oilorfgas toifonmfa fuel gas which is forced underpressure'through the pipe, and lis ignited `as is 'usual rn 'burnverslof the Bunsen type. The'i'gn-ilted gas 1s forced under pressure directlydownwardly distributes the iflame and 'deflec'ts the :saline evenly against ithe'wal-ls 9, fof the fire chamhich'in turn evenly hbcigfrom `whence it passes Over-the retainand 6, into the heating chaming Walls 5 bers. n Y n .i j

If it is desired to 'heatfone end of one chamber only, the hhap-'lfbutterflylvalve is operated tohalfgclosethe burner and in" this position open half of the Vburner is rotated until the the burner is directed toward the end of the chamber to be heated. When adjusted this ivay, all Aofthe flame is directed to one siderand one end of the de V `fle'ctor Wall"8, from Where in' turn the `iame is directed to the desired chamber. If the same ends of tivo different chambers are to be heated simultaneously, the burner is turned until the open half thereof is directed equally to the chambers, that is, the butteriiy valve lies transversely of the deflector Wall with the open side toward the ends of the chambers to be heated. In this position, the flame is directed toward cor responding ends of the fire chambers and is distributed equally on both sides of the' deflector.

Now, assuming that material in the same ends of tWo chambers is to be treated simultaneously but at different degrees, the burner is rotated so that the open half of the valve is diagonallyT directed across the defiector Wall in which position the flame is divided by the, deflector and deflected to the same ends of the chambers but at different degrees. It will be seen by the construction set lforth that any heating chamber or combination thereof can be heated independently of the others, and that articles in different chambers may be consecutively treated While those previously treated arebeing used, or in fact, any desired heating arrangement is obtainable. The retaining Walls, of course, lpre- .vent any of the articles such as rivets,

knuckles, or any other articles into the fire chamber.

In the construction from falling shown in Figs. 9 to 12, inclusive, the same results are obtained by operating the pipes 40 and 49, to swing the nozzle 4l, as desired. This nozzle can be universally adjusted within the necessary limit of adjustment required by virtue of the connections 44, 47 and 48, hereinbefore set forth. l

In the construction shown in Figs. 13 and 14, the burners are of any of the types described herein, and the operation of the iire chamber and deflector Wall is substantially as ,hereinbefore set forth.

We are aware that various details of construction inay be varied through aY Wide range Without departing from the principles of this invention, and We therefore do not purpose limiting the patent granted other- Wise than necessitated by the prior art.
